Cách sử dụng
The expression "drop/dump something in somebody’s lap" means to give someone a responsibility or problem unexpectedly or suddenly. It can be used when someone is not prepared or willing to take on a particular role or task, but is forced to do so because someone else has given it to them without warning. It is usually used in a negative context, when there is a sense of frustration or unfairness involved. For example, "My boss dropped a massive project in my lap just before the weekend, and now I have to work overtime to finish it."
